I am female and I've had to confess sexual sin, and it was embarrassing at first. At the time I contemplated whether being crucified would be less painful.
I wondered if the priest would think I was overly disordered because I was a female. I have also in confessions since just used the term, sexual sin. And the priest hasn't asked for further details. No priest I've had to confess sexual sin to has blinked or jumped back in shock or said anything negative. They don't. Priests want us to come to the sacrament of Confession. They want to help us loosen the rift that sin has caused between ourselves and God.
I am so glad I managed to find the courage to go to Confession that first few times, because the grace given to me has really helped my spiritual growth and becoming closer to God.
The first few times are the hardest, but it does get easier after that. And it feels like a big weight has been removed from our shouders. In my case I felt lighter and more free.
I'd be here all day if I had to explain the positive spiritual benefits I have encountered after attending the sacrament of reconciliation, but I am so glad I managed to do so those first few times, although they were hard, understand that a few moments of courage can go a long way to a new life.
The confessional is not the torture chamber, although in my case I initially viewed it as thus. The true torture chamber is that tomb that sin has kept us in. But satan likes for us to think that his tomb is the comfy one, and the confessional is the scary place. But it is satan who is the one who finds the confessional as the scary place, because once a person steps into the confessional, satan knows that he is losing bit by bit his grip on keeping us in his tomb of sin and spiritual darkness.
Walk to the light, God will grant you the courage if you seek it. Let Satan be the scared one.
